Basic principles of protection against static electricity during anti-static process
Anti-static can be divided into preventing static electricity generation and preventing electrostatic damage. Electrostatic protection is a long-term system engineering. Any mistake or omission in any link will lead to the failure of static protection work. The main measures for electrostatic protection during production are electrostatic leakage, dissipation, neutralization, humidification, shielding and grounding. The human body electrostatic protection system mainly consists of anti-static wrist straps, ankle straps, overalls, shoes and socks, caps, gloves or finger sleeves. It has functions such as electrostatic leakage, neutralization and shielding. Ground anti-static treatment mainly includes anti-static ceramic steel-based composite raised floor, anti-static all-steel raised floor, anti-static porcelain floor tile and so on. Grounding is very important to reduce the static charge generated on the conductor. The human body is a conductor and is the source of the main static electricity. Therefore, we must reduce the static charge generated by people who are exposed to sensitive anti-static components or components. It is best to prevent static electricity from being generated on the human body through the human body. Several personal grounding devices: In the industry, the wrist strap is the most commonly used grounding device. The wrist strap will safely and effectively remove the static charge from your body, and the proper use of a wrist strap requires proper contact with the skin. A dirty or loose wrist strap may retain the static charge that is leaking, rendering the anti-static control ineffective. Conductive footwear or foot grounding can be used or supplemented with insufficient wrist straps. The workstation grounding device's conductive or static dissipative work surface is an integral part of an electrostatic safety workstation, especially where the hand assembly takes place, when using a wrist strap, for a clean work surface and properly connected to a common point Grounding is necessary. Conductive or static dissipative materials can generate static charges, but when properly grounded, they can effectively drain static charges.
